Seminar about "A NOVEL CHAOTIC ENCRYPTION SCHEME FOR COLOR IMAGE DATA" at Computing Faculty in Rabigh


Mr Nashwan Alromema  presented a seminar about A NOVEL CHAOTIC ENCRYPTION SCHEME FOR COLOR IMAGE DATA" at Computing and Information Technology Faculty in Rabigh on Monday 17/10/2011 at 12:00 noon at new FCITR meeting room. FCITR Dean Dr. Sami Halawani attended the seminar with the faculty members.
The following is a brief of the seminar:
In image cryptography, recently numbers of effective chaos-based image encryption schemes have been proposed. These encryption schemes are structured as permutation and diffusion stages performed alternatively. In this project we will propose an encryption scheme for encrypting colored image data. This encryption scheme is based on chaotic confusion, where every pixel in the image will be first extracted to its RGB triple, encrypted, and prepared to be sent in unsecured channel. Selective key should be presented during the encryption process. This key is in the form of another chosen image with the same size of the plain image that we intend to encrypt. Image encryption scheme introduced here is based on chaos’s method, which is applied on RGB component of the image pixel. A chaos-based cryptosystem scheme will be proposed in order to reduce the encryption/decryption time and achieve high level of security.
